Serial port communication

We're running SCO Unix Openserver 5.05 and I'm having trouble with serial communication between the com2 serial port and a handheld device. Downloading data from Unix to the handheld works perfectly, but the other way around creates a major problem. I don't know whether it's a buffer overflow or what, but it looks as if the handheld sends the data faster than Unix can read it. Flowcontrol? Anybody? Please help.

What kind of handheld device? What's the port you are connecting to? /dev/tty2a or /dev/tty2A ? Look in /etc/inittab and look for the line that has /dev/tty2a or /dev/tty2A and see if a getty process is respawn on that port ? What's the baud rate set on the port? What kind of wiring protocol do you have ? Xon/Xoff ?
